2 Claims.

This invention relates to wood working machines, and particularly tomachines known as sanding machines wherein a sanding wheel is supportedon a rotating shaft, and against which the work is held during thesanding operation.

The primary object of the invention is to provide a machine .of thischaracter including a motor operated shaft on which the sanding wheel ismounted, means being provided for adjusting Q 20 invention resides inthe combination and arrangement of parts and in the details ofconstruction hereinafter described and claimed, it being understood thatchanges in the precise embodiment of the invention herein described, may25 be made within the scope of what is claimed,

without departing from the spirit of the in-' vention. Y Referring tothe drawings:.

Figure l is a side elevational view of a sanding machine constructed inaccordance with the invention.

Figure 2 is a front elevational view thereof.

Figure 3 is a view in elevation of the motor support.

Figure 4 is a-sectional view taken on line 4-4 of Figure 1.

, Figure 5 is a sectional view taken on line 5--5 of Figure 2.

Figure 6 is a fragmentalplan view of the machine, illustrating thestationary table'top.

Referring to the drawings in detail, the machine embodies a frameindicated generally by the reference character 5, the frame having astationary table or top 5, which is formed with 45 a circular opening Ithat is of a diameter slightly greater than the diameter of the sandingwheel 8.

. This sanding wheel is mounted on the free end of the motor shaftindicated at 9, which shaft 1 extends from the motor ill, in the usualand well 50 known manner. An opening indicated by the erence character Hextends from one edge of theitabie a, and terminates at the opening 1,so

thatIthe motor shaft 8 may swing therethrough,

when: the motor is from a vertical positioiafto a horizontal position.

The reference character I2 designates a. supporting shaft which ismounted on the frame of the machine 5, the shaft l2 being mounted insuitable bearings of the leg members of the frame. Mounted on one end ofthe shaft I2 is a pinion 5 [3 that meshes with the worm l4, mounted onone end of the shaft l5, there being provided a crank handle IE, onone'end of the shaft l5, whereby the shaft l5 may be rotated to rotatethe shaft l2, for purposes to be hereinafter more fully dem scribed.

The motor support, includes a base plate I! that is formed with ribs l8disposed along its longitudinal side edges. This base plate i1 ismounted on the shaft 12, through the medium of the bracket l9 that isbolted to the base plate ll, by means of the bolts 20. This bracket I8is secured to the shaft l2, by means of the set screw 2|, with theresult that the motor may be accurately positioned with respect to theshaft i2.

Plate 22 also forms a part of the motor support, and is provided withbeveled side edges, fitted under the ribs i8.

One end. of the base plate I! extends at right angles, "where it isprovided with an opening through which the threaded shaft 23 extends,

, 't'he shaft 23 also extending through a threaded opening in the plate22, as clearly shown by'Figure 5 of the drawings. On one end of theshaft 23 is a crank handle 24 whereby the shaft 23 may be readilyrotated to move the plate 22 of the motor support, longitudinally of thebase plate H, to adjust the motor with respect to its support.

The reference character 25 designates the bench or work rest formingapart of the machine, and as shown,this bench or work rest 25 includes abracket 26 that extends downwardly and is provided with an extensionflformed with a threaded opening, through which the threaded o shaft 28extends. This shaft 28 is supported in the lug 29 extending from theframe of the machine, the shaft 28 being provided with a handwheel 30,whereby the shaft 28 may be rotated.

It is obvious that when the shaft 28 is rotated, the bench or worksupport 25 will be moved vertically,= so-*that the work may be supportedon the bench 25 in an adjusted position,.with respect to the sand wheel.

A set screw indicated by the reference char- 5o acter 31 extends throughthe extension 21, and is adapted to engage the shaft 28, securing the'bench or work support 25, in its adjusted positions.

As clearly shown by Figure 2 of the drawings,

the bracket 26 of the bench or work support 25, moves under the flangeplates 32 that are secured to the frame of the machine, the plates 32acting as guides for the bracket 26 of the bench or work support 25.

From the foregoing it will be understood that due to the constructionshown and described, the sanding wheel may be readily and easily movedfrom a vertical position as shown by Figure 1 of the drawings, to ahorizontal position, wherein the shaft 9 operates in parallel relationwith the bench or work support 25, adapting the device for use insanding articles wherein it is necessary to support the articles atvarious angles with respect to the sanding wheel.

I claim:

*1. In a sanding machine, a frame, including a table having an openingextending inwardly from one edge thereof, a motor support including abase plate having flanges formed along the edges thereof, said flangesforming guides, a slide slidably mounted on the base plate, the sideedges of the slide moving under the flanges, said slide having athreaded bore, athreadedshaft supported on the base plate and movable inthe threaded bore, a motor mounted on the slide, a shaft driven by themotor and adapted toswlng through the opening, a grinding wheel on theshaft, said threaded shaft adapted to be rotated for adjusting the motorand shaft with respect to the table, and means for swinging the motorand motor shaft from a vertical position to a horizontal position.

2. In a sanding machine, a frame, a table forming a part of the frameand having an elongated opening extending to one edge thereof, avertically adjustable pivoted support'mounted on the frame, a motormounted on the support and adapted to swing laterally with respect tothe table, a shaft extending through the table and adapted to movelaterally through the elongated opening to assume a horizontal position,a sand-' ing wheel on thefree end of the shaft, and means for swingingthe motor laterally whereby the sanding wheel may be operated in variouspositions from a vertical to a horizontal plane.
